WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 567,498, datedSeptember 8, 1896. Application filed .Tune 19, 1893. Renewed February27. 1896. Serial. No. 581,081. (No model.)

To all whom it may/concern:

Be it known that I, ARTHUR OBnmn, a citizen of the United States, and aresident of the city of Helena, county of Lewis and Clarke, State ofMontana, have invented a new and useful Improvement in Water-Closets, ofwhich the following is a specification.

The cleaning and Ventilating of waterclosets is an important feature inimproving the sanitary condition of buildings. My invention is intendedto promote both by a combined hinge and ventilatin g arrangement.

Similar letters refer to similar parts in all the drawings.

Figure l is a plan View of seat, hinge, and pipes. Fig. 2 is a sideelevation, in section, on line a: y. Fig. 3 is a side elevation ofhinge-piece. Fig. 4 is a rear elevation of pipe in seat and hinge-piece.Fig. 5 is a front elevation of pipe in seat and hinge-piece.

The metal hinge-pieces A A each have two slots a a cut upon their innersurfaces, as shown in Fig. 3, and a screw B upon the back forpenetrating the wall and screwing into the pipes C O. rIhe screw B ishollow and the air-passage M continues through the piece A, opening intothe lower slot a' at n. Passing horizontally through the rear of theseat D is the pipe E, closedat the ends. Y The ends project and act aspins c c for engagement in the slots o. a', and thus form the hinge onwhich the seat swings. In this pipe E is a slot or opening e at thecenter, facing the slot d, which is cut in the wood of the seat D andopens into the bowl F. Near each end of the pipe E are openings g g,which correspond and t'to the openings n n in the slots a' a', thusforming continuous closed airpassages from the bowl F to the pipes O C.These pipes C O are closed at one end, and at the other end fit into themain Ventilatingpipe P. The seat D has a rubber gasket o around it, thusfitting closely upon the bowl F. The cover G has two pins h, one uponeach side, that engage in the upper slot-s a a, of the pieces A A, thusforming the hinge for thecover. It is thus seen that my invention servesboth as a hinge for seat and cover and as means for Ventilating thebovvl when the seat is down. construction and permits both seat andcover to be readily removed for cleaning or repairing parts orconnections. The smooth outer face of the pieces A may be nickle-platedand add neatness to the appearance of the apparatus. If preferred, onlyone of the metal hinge-pieces A need have the air-passage andconnections with the bowl and Ventilatingpipe. The hinge may also beused apart from the Ventilating function where proper connections cannotbe made. f

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- l. In awater-closet the combination witha metal hinge-piece flXedly secured and having two vertical slots and anair-passage leading from the lower one of said slots to aventilating-pipe, a cover having a pin engaging the upper slot, and aseat having a slotted pipe the ends of which project and engage the Thehinge' is very simple in lower slot substantially as and for the purposeset forth.

2. In a water-closet, a seat, slotted in the rear portion a slotted pipein said seat, having projecting ends, a hinge-piece, slotted to receivethe said ends, and having a screw, an air-passage through the screw andhingepiece to the slot, and a Ventilating-pipe, all substantially asshown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this lthday of March, 1893.

EDWARD C. RUSSEL, CHARLES W. HELMIGKT.
